Backstops for Belt Conveyors and Bucket Elevators

High Speed Backstops are located on the 2nd or 1st gearbox reduction shaft and prevent reverse motion of conveyor belts or bucket elevators.

They are equipped with sprag lift-off X which ensures a wear free freewheeling operation when the backstop is rotating at high speeds with the gearbox shaft. In this state of operation, the backstop works wear-free, i.e. with unlimited service life.

High Speed Backstops with Torque Limiting are used in belt conveyors with multiple drives and prevent reverse motion of conveyor belts.

They solve the problem of uneven load distribution in multiple drives.

They are equipped with spraglift-off X which ensures a wear free freewheeling operation when the backstop is rotating at high speeds with the gearbox shaft. In this state of operation, the backstop works wear-free, i.e. with unlimited service life.

Maintenance free

The integrated torque limiters protect the gearboxes and backstops from overload by dynamic peak torques.

Smaller gearboxes can be used without negatively effecting the safety.
